Mobile app development

A mobile app is judged in thirty seconds, then lives or dies on whether it keeps working. We build products that do both.

What this includes

Native iOS

Swift and SwiftUI applications built to platform conventions, not a web page in a wrapper.

Native Android

Kotlin applications that respect Material behaviour and the range of devices your users actually own.

Cross-platform

React Native or Flutter where one codebase genuinely serves both platforms, and honest advice when it does not.

Release and beyond

App Store and Play Store submission, staged rollout, crash monitoring, and the updates that follow.

Four things that exist when we are done.

  1. Applications submitted and approved on both stores

  2. Offline behaviour and error states designed, not left to chance

  3. Analytics and crash reporting wired in before launch

  4. A release process your team can run without us

Questions we get asked

Ask us something else

It depends on how much of your product is platform-specific. Cross-platform is a genuine saving for content and workflow apps; it costs you more than it saves once you need deep platform integration, heavy graphics, or background behaviour. We give a recommendation in discovery rather than defaulting to whichever we prefer.

Yes, including the parts that surprise people: privacy nutrition labels, review responses, staged rollout, and the rejections that come from guideline details rather than code.

Often. We start with a technical audit to establish what is salvageable and what is costing you more to maintain than to replace, then give a recommendation with the reasoning behind it.
